“…These devices exhibited high radiance (143-303 µW cm −2 ) and EQE (0.26-0.57%) for an EL peak wavelength >800 nm. [22] However, for many applications, it is preferable to employ emitters that are free from expensive and rare metals in the Pt group, [23] and in this context Pertegas et al [24] reported LECs comprising two cyanine dyes as the host-guest blend, which featured a radiance of 170 µW cm −2 at a peak wavelength of ≈700 nm and an EQE of 0.44%. Tang and coworkers [25] reported the synthesis of a donor-acceptor copolymer, which was employed as the single-emitter in a NIR-LEC that delivered a radiance of 129 µW cm −2 at a peak wavelength of 705 nm and a low drive voltage of 3.4 V. Finally, Murto et al [13b] incorporated a set of designed polymeric emitters in host-guest LECs, which exhibited a high radiance of 1500 µW cm −2 at a peak wavelength of 725 nm.…”

The synthesis of 5,10,15,20‐tetrakis((5,10‐bis((2‐hexyldecyl)oxy)dithieno[3,2‐c:3′,2′‐h][1,5]naphthyridin‐2‐yl)ethynyl)porphyrin zinc(II) (Por4NT), a near‐infrared (NIR) emitting compound, comprising a zinc porphyrin core linked with triple bonds through its meso positions to four 5,10‐bis((2‐hexyldecyl)oxy)dithieno[3,2‐c:3′,2′‐h][1,5]naphthyridine (NT) arms is reported. Por4NT featured high solubility in common non‐polar solvents, which is ideal for easy processing through solution techniques, and high photoluminescence (PL) efficiency of ≈30% in dilute toluene solution. It also exhibited a strong tendency for aggregation because of its flat conformation, and this aggregation resulted in a strong redshifted emission and a drop in PL efficiency. A well‐matched PBDTSi‐BDD‐Py “host” terpolymer is therefore designed, which is capable of mitigating the aggregation of the Por4NT “guest”. An optimized blend of the host, guest, and an ionic‐liquid electrolyte is utilized as the active material in a light‐emitting electrochemical cell (LEC), which delivered strong NIR radiance of 134 µW cm‐2 with a long wavelength maximum at 810 nm at a low drive voltage of 5.0 V. The attainment of the strong NIR emission from the host–guest LEC is attributed to a tuned aggregation of the Por4NT emitter, which resulted in the desired aggregation‐induced redshift of the emission at a reasonably retained efficiency.

“…PGMs are transition metals in the d -block of the periodic table that have valence shells of 6s 1 5d 9 , 4d 10 , and 5s 1 4d 8 for Pt, Pd, and Rh, respectively. Consequently, they exhibit similar paramagnetic properties and a strong tendency to form similar kinds of complexes . According to the hard–soft acid–base (HSAB) theory, these metals show soft-acid characteristics; thus, they prefer to coordinate with soft-base ligands, e.g., cyanide, amine, ammonia, and sulfur ligands, as well as halides.…”

Mutual separation of platinum group metals (PGMs) is a particularly challenging issue in metal recovery technology. In this study, we report the successful separation of Pt(IV), Pd(II), and Rh(III) by sequential transport through polymer inclusion membranes (PIMs) containing the ionic liquid trioctyl(dodecyl) phosphonium chloride (P 88812 Cl) as a metal carrier. This study describes the screening of suitable receiving solutions, optimization of the operating conditions, establishing a possible transport mechanism, and evaluation of the membrane stability. In the first transport sequence, Pt(IV) was selectively transported into the receiving solution with a recovery of >95%, while Pd(II) and Rh(III) remained in the feed solution. In the second transport sequence, high-purity Pd(II) was transported into the receiving solution with a recovery of >95%, while Rh(III) remained completely in the feed solution. Furthermore, the PIM exhibited a stable performance with multiple uses over a 4-week period during which four Pt(IV) and Pd(II) sequential transport cycles were continuously carried out.

This data article is associated with the research article “Technical and environmental analysis on the power production from residual biomass using hydrogen as energy vector”. This paper shows the procedure to calculate the Life Cycle Inventory (LCI) of the foreground system to perform the Life Cycle Assessment (LCA) of the power production from sugarcane press-mud. Said process encompasses four main stages: i) bioethanol production; ii) bioethanol purification; iii) syngas production and purification; and iv) power production. Additionally, other processes such as biomethane production and manufacturing of catalyst were included. Foreground data related to bioethanol production was gathered from experimental procedures at lab-scale. While foreground data, concerning the other processes such as bioethanol purification, syngas production and purification, power production, and biomethane production, was built by using material and energy flows obtained from Aspen Plus®. Lastly, LCI of the catalyst manufacturing was built based on literature review and the approach stated by Ecoinvent. All the inventories are meaningful to carry out future environmental assessments involving sustainable energy systems based on bioethanol, biomethane, or hydrogen.
